PY2071ASI-571

Programmable Timers And Oscillators Overview

The CY2071ASXL-XXX is a Single-PLL General-Purpose EPROM Programmable Clock Generator manufactured by Cypress Semiconductor. It features a single phase-locked loop architecture and EPROM programmability, allowing for factory-programmable (CY2071A, CY2071AI) or field-programmable (CY2071AF, CY2071AFI) device options. The component provides up to three configurable outputs with low skew, low jitter, and high accuracy. It includes an internal loop filter, power management via OE, frequency select options, and supports configurable 5V or 3.3V operation within an 8-pin 150-mil SOIC package.

Programmable Timers And Oscillators Procurement Notes

Verify the exact suffix of the part number against official Cypress documentation to confirm programming type (factory vs. field) and voltage specifications. Ensure compatibility with input frequency ranges of 10 MHz–25 MHz for external crystals or 1 MHz–30 MHz for reference clocks. Confirm package integrity for the 8-pin SOIC form factor.

Programmable Timers And Oscillators Selection Notes

Select based on required output count and programmability needs. Choose factory-programmable variants (CY2071A/AI) for fixed designs or field-programmable variants (CY2071AF/AFI) for flexibility. Verify input source compatibility, either external crystal or reference clock, and ensure voltage levels match system requirements of 3.3V or 5V.

Programmable Timers And Oscillators Part Context

The CY2071A series belongs to Cypress's general-purpose programmable clock generator family. These devices are designed to alleviate the need for multiple discrete timing components by integrating PLL functionality and EPROM storage in a compact package. They support industry-standard design platforms and offer easy customization with fast turnaround times.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes depend on specific configuration parameters such as output frequencies and voltage levels. Review datasheets for other Cypress CY2xxx series clock generators to identify compatible alternatives with matching pinouts and electrical characteristics.
